圣诞节前夕,一个富裕人家正在忙着筹备圣诞。窗外白雪皑皑,屋里迎来了女儿大学归来。一家人沉浸在圣诞前团聚的气氛。 此时,大家以为作为一家之主的父亲还没有睡醒,谁知打开房门一开,他竟死在了睡床上,背后插着一把刀。众人惊慌失措,想报警之时却发现电话线早以被剪断;车已被蓄意破坏,无法开到警局。明显地,凶手就在这8人中间。彼此的猜忌和指控开始了,各人不为人知的秘密一一曝光,伦理道德的颠覆,贪婪自私的本性,令这个圣诞前夕特别混乱。讽刺的是,最后谁是凶手已经不重要了……One morning at an isolated mansion in the snowy countryside of 1950s France, a family is gathered for the holiday season. But there will be no celebration at all because their beloved patriarch has been murdered! The killer can only be one of the eight women closest to the man of the house. Was it his powerful wife? His spinster sister-in-law? His miserly mother-in-law? Maybe the insolent chambermaid or the loyal housekeeper? Could it possibly have been one of his two young daughters? A surprise visit from the victim's chic sister sends the household into a tizzy, encouraging hysterics, exacerbating rivalries, and encompassing musical interludes. Comedic situations arise with the revelations of dark family secrets. Seduction dances with betrayal. The mystery of the female psyche is revealed. There are eight women and each is a suspect. Each has a motive. Each has a secret. Beautiful, tempestuous, intelligent, sensual, and dangerous...one of them is guilty. Which one is it?
